The Five Sunscreen Habits That Cut Skin Cancer Risk Most
Evidence-ranked, not vibes-ranked.
Invasive melanoma diagnoses rose ~46.6% over the decade 2016-2026 (Skin Cancer Foundation).
Five or more sunburns roughly doubles a person's lifetime risk of melanoma.
Frequently asked questions
What are the early warning signs of melanoma?
Watch for the ABCDEs: Asymmetry, irregular Borders, uneven Color, Diameter over about 6 mm, and Evolving (changing) spots. Also note any 'ugly duckling' mole that looks different from your others, or a sore that won't heal. See a dermatologist promptly about anything new or changing.
How often should I get a skin check?
Examine your own skin about monthly, and see a dermatologist for a professional check at least yearly — more often if you have many moles, fair skin, a history of sunburns or skin cancer, or a family history. Early detection makes melanoma highly treatable.
What does the ABCDE mole rule mean?
ABCDE is a checklist for spotting possible melanoma: Asymmetry, Border irregularity, Color variation, Diameter greater than about 6 mm (a pencil eraser), and Evolving size, shape or color. Any mole meeting these — or simply changing — warrants a dermatologist's evaluation.
